This is basically what happens when you binge watch all seasons of Sherlock and then find inspiration for a drabble... *sigh* Combining Sherlock (which I do not own) and TVD (which I also do not own) is like perfection, or at least in my head... Anyhow, Kluas is Sherlock, Stefan is Watson (which would be soooo cool in my opinion, but I mean Benedict Cumberbatch...). This is totally AU from both shows, but I liked the idea of a Klaus and Stefan Sherlock Holmes, so here it is. It's a bit more angsty than my other drabbles, and I'm not even sure where that came from but, alas, it is here and I am updating (I know, crazy right!) And did you see that beauty of a cover? Well that was made by the lovely nfinneman, so a shout out to her! Alright, I now give you permission to stop reading my unnecessarily long authors note and read.

Stefan can't remember the last time the apartment was this quiet. It's always this or that – Klaus pacing in the living room, Klaus typing on the computer, Klaus having target practice against the wall – anything, really, but now there's just... silence.

It all started with a phone call.

Klaus was staring at his wall of clues when the phone rang.

Stefan walked towards the noise, as he knew Klaus wouldn't answer it when he was in the zone like he was, but to his great shock and dismay, Klaus' head whipped around and he stared wide-eyed at where the noise was coming from – only then did Stefan realize that it was a different ring-tone than Klaus' regular cell.

Klaus was frozen in his spot, but then seemed to come back to his senses and ran towards the phone.

Stefan stood there confused as he picked it up – "Hello." A pause. "I'll be right there." – and hung up.

Next thing Stefan knew, Klaus was grabbing his coat and running out the door, so he did the only thing he could and followed him.

Klaus was just getting into a taxi when Stefan caught up to him and climbed in on the other side. Klaus didn't spare him a second glance as he told the taxi driver to go to the London Hospital for the Mentally Insane and to step on it.

Stefan was officially confused at this point but chose not to ask any questions as Klaus looked genuinely... worried. And worried was not an emotion that Klaus Mikaelson portrayed often, if ever.

The ride was deafeningly quiet, with the only sounds being the breathing of the taxi's occupants and Klaus' constant tapping of his index finger to his knee – a nervous habit. But Klaus nervous? Something must be seriously wrong, Stefan thought.

After about five more minutes, the taxi stopped outside the mental institute and Klaus burst out of the car doors and straight into the hospital, leaving Stefan to pay the taxi driver and run after him.

The lady at the front desk seemed to recognize Klaus as she handed him a visitors' pass as he ran passed her desk and down the hallway, an obvious destination in mind. Stefan ran after him, ignoring the woman's yells for him to come back, and found himself outside the room of one of the patients.

He looked inside to see a blonde woman thrashing on a bed, surrounded by bulky looking men in white scrubs trying to contain her. The woman continued to kick and scream until a moment later she stopped completely. Her eyes were glued to a single figure kneeling next to her bed, and only then did he notice that it was Klaus.

The woman stared for a moment longer until a tear fell down her cheek. Then another, and another, until she was full on sobbing. Klaus was quick to react and held the woman to his chest, gently stroking her hair and whispering sweet nothings into her ear, as if he'd done it a million times before. And perhaps he had, for all Stefan knew, as Stefan was beginning to learn that there were a lot of things he didn't know about Niklaus Mikaelson.

The room was quiet, save for the girl's sobs that were slightly muffled by Klaus' coat, as the guards began to slowly shuffle out, save for one who stopped by the door near Stefan. The two men looked away from the scene in front of them, feeling as if they were intruding on a private moment.

This gave Stefan some time to think about who the girl might be. She was obviously important to Klaus, as Stefan had never seen him act this way in the least. Maybe she was his sister? No. Stefan had met Rebekah, and despite the blonde hair, this was obviously not her. A close friend? Did Klaus even have friends? Well, Stefan guessed he could consider himself one, but even he knew Klaus didn't make friends. A lover perhaps? Lost love? Negative. Stefan distinctly remembered Klaus saying "love is a man's greatest weakness", and Klaus Mikaelson doesn't have weaknesses... right?

The creaking of a bed broke Stefan out of his musings. He looked up to see Klaus now laying against the headboard with the blonde woman clinging to him for dear life. He could barely make out Klaus' quiet mutters of "It's alright, love. I'm here now. It was just a nightmare," but he heard it nonetheless. Nothing was making sense to Stefan, and if spending almost six months now as Klaus' apprentice taught him anything, it was to get to the bottom of every and any mystery you come upon.

Stefan was getting ready to storm up to the bed and demand answers from Klaus, when the woman from the front desk came up to him and whisper-yelled, "Sir, I think it's time for you to leave. Mrs. Mikaelson has been through a lot, and some alone time with Mr. Mikaelson is all that she needs. Not some stranger barging in unannounced and causing her more stress. Now if you'd kindly leave, it'd be much appreciated, otherwise I will have to have Enzo here show you out." She looked towards the man in white scrubs by the door and back at Stefan pointedly.

His eyes were wide with shock, however, at the woman's words. Did she say Mrs. Mikaelson?

Stefan realized that she had. That means Klaus is married – Klaus, married, how is that even possible? Unless she's married to one of his three brothers, but that doesn't look like the way a man holds his sister-in-law. Thoughts and questions were running through Stefan's head, trying to make sense of things, but he only became more confused.

Stefan looked up towards the woman who was standing with her hands on her hips and an unimpressed look on her face. He then spared a glance towards the bed and realized that now might not be the time to demand answers. It would be brash and impulsive and all things Klaus, though as Stefan was learning, might not always be the case. So, with one last look at the couple on the bed, Stefan silently walked out the doors with the woman following to make sure he left.

He walked out the front doors, and got into a taxi, making his way back to his and Klaus' apartment.

Stefan didn't sleep at all that night. He laid in bed with thoughts of the mysterious blonde running through his head. Apparently she was Klaus' wife, but since when was Klaus married? Sure, he never brought women home or acknowledged their advances, but Stefan thought that was just his personality.

No one had ever mentioned a wife before, but maybe they didn't know either. The only thing Stefan knew for certain was that he would get to the bottom of this and find out all that he needed to know.

Klaus came home around ten in the morning to find Stefan awaiting him on the couch, no doubt waiting for answers.

He didn't want to divulge his past with Stefan, but he knew how stubborn Stefan could be when he wanted to know something. Not as stubborn as Caroline, though. No one was more stubborn than her, he thought. His lips twitched at the thought, but his face was once again stoic as he sat on the couch across Stefan and looked at the man he had come to know as a friend. The two stared at each other for a moment, neither wanting to break the silence.

Klaus finally decided that he was going to have to tell Stefan anyway, so he'd be better off getting it over with.

"I suppose you wish to know who the women at the hospital last night was."

Stefan only nodded, allowing him to continue.

"Well, she is my wife. Caroline."

Stefan nodded hesitantly. "Well, when the lady at the front desk referred to her as Mrs. Mikaelson, I figured as much, but I never even knew you were in a relationship, let alone married. And to a girl. I mean, don't get me wrong, but you don't even spare a glance at women when they pass by and I was starting to think you might be gay, or asexual."

Klaus chuckled at this. "No, Stefan, I am completely straight, not that I have anything against those things, I just don't see the need to look at women when I already have one of my own."

Stefan could understand that for the most part. Klaus seemed to really care for his wife, and Stefan was glad to know that Klaus Mikaelson was more than just a phenomenal detective, but also a caring and loving husband. This brought up another question though. "I thought you said 'love is a man's greatest weakness'?"

Klaus paused for a moment before replying, "I did, though I never said I was free from weakness."

Stefan contemplated this for a moment. It was true that Klaus had never outright said that he had never loved. In fact, Stefan had seen it when Rebekah or Elijah came by to visit. It all just brought upon more question, however.

One thing Stefan really wanted to know was why Klaus' wife, Caroline, was in the mental hospital, but he figured he should start off slow so as not to scare off Klaus completely.

"So how did you two meet?"

Klaus smiled fondly at this, "Well, it's rather comical. She was my neighbor, you see..."

"I know I put it somewhere" Caroline mumbled to herself, looking through the boxes for her hair curler. She had just moved in the day prior, and hadn't gotten around to packing quite yet. But after breaking up with her cheating douche of a boyfriend, Tyler, she decided to move on with her life and see some of the world. She had been accepted to Oxford, but Tyler had convinced her to stay – which she had all of freshman year. But with him out of her way, she was free to do as she pleased. So, she hopped on the next flight to England, with a call to her mother and friends of course, and spent a week searching for apartments that fit her budget. Finally, she had found one close to school that wouldn't cause her to go bankrupt, and thus, 220 B Baker Street became her new home.

A loud gun shot caused Caroline to jump, simultaneously knocking over the box she was looking through and causing her to fall and land on her butt. She sat there for a moment before another gun shot rang out, and she leaped into motion. She knew it wasn't the best idea to go running towards gunshots, but someone could be hurt.

She ran out of her front door as another shot rang off, this time she could clearly tell it was coming from her next door neighbor, and yanked said neighbor's door open. However, she froze at what she saw.

A shirtless man – with a lovely backside, Caroline thought – was shooting a... target on the wall. He had heavy duty earphones on, and was wearing nothing more than a pair of dark black jeans and a few necklaces around his neck. The man turned around to look at the intruder, and Caroline saw that he had an even lovelier front side – so not the time, Caroline. The man had a few tattoos covering his chest, and was well-sculpted. He had curly blonde hair that made Caroline want to run her hands through it, and the bluest eyes that made her want to get lost in them forever. But Caroline shook her head of these thoughts. She was on a mission.

As soon as the man placed the gun on the table, and took the earphones off his head, Caroline exploded. "What the actual fuck?! Why in god's name are you having target practice in your living room at-" she looked at the clock on the wall "five fifteen in the morning!" She looked at the man with rage in her eyes.

His only response was to look her up and down and say, "well hello to you too," and walk towards his kitchen.

"Are you even listening to me?" Caroline yelled.

"Oh, I am love, I am just choosing not to respond to your questions. You see, I feel that one should not answer people's questions when they are being hostile, as it allows them to think that their behavior is justified and alright."

Caroline sneered at this, "Are you saying that my behavior is unwarranted? Because I just walked in on you having target practice in your apartment at five in the morning, which I'm pretty sure is illegal. I'm pretty sure one of the neighbors have probably already called the police and –"

"Not likely, sweetheart." Klaus interrupted.

"What?"

"The neighbors are aware of my penchant for activities that involve loud noises and have gotten used to it. I also bought everyone in the building industrial earphones for Christmas this year. I may even have an extra pair if you'd like them, love."

"Okay first of all," Caroline started staring Klaus down, "I am not your love or sweetheart or your anything. Second of all, why are you shooting at five in the morning, and why do you even have a gun? Are you a cop or something?"

"Well, I find that shooting helps me to relax." Caroline raised an eyebrow at this. "And no love, I am not a cop." He said with a smirk.

"So let me get this straight. You shoot guns for fun, and you're not a cop?" She asked.

"Yes." he replied. The two looked at each other for a moment before he continued, "You are the new tenant next door, am I right?"

"No shit, Sherlock." she replied.

"Actually it's Mikealson. Niklaus Mikealson, but you, sweetheart, may call me Klaus."

"Caroline had just moved over from America, quite like you. She lived in a small town in Virginia called Mystic Falls, but she was too good for a small town like that. She was very intelligent, brilliant in fact, and had a very bright future ahead of her. She was studying psychology at Oxford, and had the highest marks in her class. She was only nineteen and I twenty three when I met her, but I could already tell that she was going places.

"She didn't like me very much, or so she said, but I was captivated from the moment I saw her. She was absolutely beautiful and had this light about her that lured in even the darkest of souls. After learning about my work and even seeing me in action, she agreed to become my apprentice, much like you are now, as she was quite intrigued by my detective work. I attempted to win her favor for months, but she continuously refused my advances. That was until a wondrous Saturday afternoon..."

"What the hell was that for Klaus?" Caroline screeched.

"Well, love, that man was trying to ask you out." Klaus answered easily.

"Yes, I got that. And you told him I used to be a man because...?" she asked angrily.

"He was not good enough for you."

"And you are?"she yelled.

He paused for a moment. "No."

"Why do you even care?" she asked exasperated.

"I fancy you." She looked up shocked. "You're beautiful, strong, full of light. I enjoy you. Is that so hard to believe." Klaus asked. She just nodded her head.

She looked down to the ground, but Klaus grabbed her chin and pulled her in for a kiss.

"... and as they say, the rest was history." Klaus smirked. "We began dating and I proposed to her two years later, but she wanted to wait until she graduated from college before we actually said 'I do'. So we did. Life was good then, she and I worked together and solved cases, and we were happy. A year after we married, we learned that she was pregnant and we were ecstatic. She would have made a brilliant mother. She always told me stories of how we'd have a dozen little blonde children running about, and we'd teach them to be little detectives, but still allow them to do whatever they wanted in life. She was such an optimist, and I find myself dreaming that that had actually happened." Klaus sighed wistfully and looked down at his hands.

Stefan had been quietly listening the whole time, not wanting Klaus to put his walls back up, yet he asked, "So, why didn't it?"

"Her brother died." Klaus said bluntly.

Stefan looked shocked, but waited silently for him to continue.

"She was only about three months pregnant at the time, but her brother was excited to become an uncle and insisted that he come visit her. Matt was three years younger than Caroline, and had stayed home for college. Caroline had practically raised him, as their father had left when they were young and their mother was at work more often than at home. He was her baby brother, and she spent her whole life protecting him, but then on his fourth day in the city, he was mugged and killed. The mugger took his wallet and then shot him. He bled to death." Klaus took a breath. "Caroline was devastated. She blamed herself for his death. She went into depression for a while, until she finally realized that she was doing nothing for Matt by just sitting around, starving herself and our baby. So she threw herself into his case. She spent countless hours trying to find anything that could lead to her brother's killer. I tried to get her to stop, to sleep. I told her it wasn't good for her or the baby, but she just wouldn't listen. She's the most stubborn person that I've ever met."

He looked up and Stefan saw his haunted eyes. He could see the pain behind it, of watching the love of his life go through all this. Stefan was starting to understand Klaus Mikaelson just a bit more.

"She was following a lead when it happened. She had received an anonymous tip, not to my knowledge, that had informed her that the man she was looking for was at this abandoned warehouse downtown. She snuck out in the middle of the night, knowing I'd never allow her to go.

"It was a drunk driver. Her car rolled eight times. She was five months pregnant. She survived but our baby did not." Once again Klaus paused, and Stefan could see that it was taking a toll on him to recount these events, so he did not push.

"It was too much for Caroline. First her brother, and then our baby. She just broke. She had nightmares and couldn't sleep. I would remind her that she still had me, and she would smile, but then remember all that she had lost and I would hold her while she cried until she fell into a dreamless sleep. And those were the good nights. Finally, the doctors recommended I put her into a mental institution, as she was starting to see things that weren't there. She claimed that her brother was following her and yelling at her for not saving him, and I just... couldn't see her like that anymore. I found the best hospital around and she's been there for the past two years.

"Most people don't know about Caroline and those who do don't speak about her out of respect for both her and myself. Those who knew her, knew that she's a wonderful person, but that she's been through too much crap for someone as pure and light as her. She was an angel, and didn't deserve for any of this shit to happen to her." Klaus finished angrily.

Stefan sat there in silence. Klaus' unwarranted anger at the world, didn't seem so unwarranted anymore. He thought of the blonde holding onto Klaus, and realized that he is probably the only good thing in her life anymore. Then he thought of something. "Wait, so is that where you go every Wednesday night?"

Klaus looked up at Stefan and gave him a wistful smile. "No shit, Sherlock."

Then it was silence.

The two men stared at each other. Stefan respected Klaus a bit more after hearing about Caroline, and Klaus respected Stefan for not pitying him.

It was a respectful silence.

That was until Klaus said, "I think she'd like you," causing Stefan to smile.

"Sweetheart, I'd like you to meet a good friend of mine."

Sooo, what'd you think? Not like my other ones huh? Well, I got inspired by Sherlock and so this happened.

I also want to apologize for taking so long to update. School has been hectic (but APs are over now!) and I haven't really found the inspiration to write lately. But look, I did a thing!

Anyway, tell me what you thought. I always love hearing from you, and if you ever have any questions, feel free to PM me.

Thanks for reading (and reviewing, hopefully?)
